GAS-BURNER.

Speccation of Letters :Patent No. 21,728, dated October 5, 1858.

To all whom t may concern:

Be it known that l, JUNIUs F. Toznn, of Binghamton, in the county ofBroome, in the State of New York, have invented an Improvement in theManner of Constructing GasBurners; and l do hereby declare that thefollowing is a full and exact description thereof.

The nature of my invention consists in providing a stop-cock to passthrough the base or thick part of the burner, which has two or more gageholes or orices through which the gas is admitted into the supplementarychamber, so that by turning it a given distance -it will vary the amountof gas to be consumed, from a two foot7 to that of a four or siX footburner.

The accompanying drawings represent my improvement.

Figure l is a plan of the burner; letter A, the stop-cock held in placein the usual. manner, by a screw at the end. All that is necessary, tochange from a two foot burner to that of a four, or six foot, is toapply a common screw driver to the groove in the end of the stop-cock;the position of this groove indicates the number of feet which theburner is then calculated to consume per hour. When the groove is atright angle with the burner tube as here represented, it is designed toconsume two feet per hour, when it is turned one quarter around and thegroove parallel with the tube the size of the orifice c.

F ig. 2 is calculated for a four foot burner, &c. Fig. 2 is alongitudinal section; letter B the supplementary chamber; c, c, theorifices in the two-way cock through which the gas enters said chamber,these orifices are graduated to correspond with the igniting aperture Dso that with the ordinary pressure of gas there will be only asufficient quantity admitted into the chamber to supply the requisiteamount for consumption. lf this chamber is too large, it is found thatit will injure the light7 and for this reason I have found it necessaryto introduce the stop-cock into the burner itself.

Fig. 3, represents the stop-cock, which should be accurately litted, toprevent the escape of gas, and kept in place by the ordinary method of ascrew and washer at the end. i

What I claim as my invention and desire to secure by Letters Patent,is-4 The application to the common gas-burner, the two, or three-wayturning-cock, for the purpose herein set forth.
